IMPROVEMENT IN SHAFT-COUPLING.

'I'O ALL WHOM I'I MAY COYCERN: p

Be it known that I, JOHN Klinsic, of Chester, in thc county of Delaware,and State of Pennsylvania,

.have invented a new and useful Improvement in Shaft and otherCouplings, of which the following is a. full,

clear, and exa-ct description, reference being had to the accompanyingdrawing, forming part of this specica.-

tion, and in vwhich-f Y Figure 1 represents an end view of my improvedcoupling as applied to connecting two lengths of shafting, vand Figure 2an irregular' longitudinal section of thc same, taken as lindicated bythe blue dotted line n: z ning. 1.

Similar letters of reference indicate corresponding parts. Y

' This, my invention, is applicable, among other purposes, to couplingshaft-ing made in separate lengths or sections lying in the same axialline; also to coupling or hanging Wheels`,'drums, or pulleys, andscrew-propcllers on their shafts ;V andA the invention' consist-s in acertain combination of wedges, bolts, and shell, box, or .hubpiece,whereby vincreased facility is afforded for establishing anddisconnecting the coupling or connection, and other advantages obtained.Y Y l I Referring to `the accompanying drawing, A represent two lengthsof shafting, which are shown united by my improved coupling, that isformed in part of a box, hub, or shell, B, geared or united by groove4and A feather or key, solas to turn with said shafts, andthatisrp'rovided or fitted on the insidctwith sliding wedgeshaped blocksC C arranged in pairs, so as to bear on either shaft on opposite sidesofV it, and thevone pair of the .one shaft having a reverse inclinationto the adjacent pair of theother shaft. These blocks C C have theirbevel on their back edges or faces that lic against inclined ways orsurfaces in the shell or box, while their front faces are liollowcd orformed to hug the shafts. D D are bolts passing through slots or holesin the Ashell B, and hooking into orlgearing with thc'wcdgc-shapcdblocks C C', and fitted on their exterior ends with nuts I E E', that.,accordingly as thcyare turned to the right or to the left, serve toslacken or tighten up the gripe of the blocks C C on thc shafts, and .soto release or establish the coupling, the sliding movement of the blocksbeing iin, direction ofthe length of thc shafts, and, by the gear ofthem with the shell and of the latter with the shafts, being restrainedfrom turning excepting with the shafts. The shell B is 4shown assupported on'the shafts A A at'stheir ends by or through a partition, b,acting as a hub. The same arrangement or means, it will be seen,

v,is or 'are equally applicable to securing wheels, drums, pulleys, orother devices on either a. single or divided shaft, it only beingnecessary to supposethe shell B, the hub of thc pulley, or other devicehung on the shaft, or it may constitute a drum or pulley itself, whetherused in addition to couple a divided shaft, or ,as arranged `on a wholeone.

By this, my improved couplingor means for establishing connection ofparts, as described, shafts can be readily uncoupled, locking-keys arcdispensed with, and as applied to a pulley, for instance, it affordsevery facility forreadily moving thc pulley from one place to another onthe shaft, and, as tbc wedges act by pairs,

in reverse directions,l for centring or holding it in its requiredposition on the shaft. In such a.` coupling there need bc comparativelylittle tting andtinishinvg, and couplings so formed be forwarded readyfor use or application, on the'diameter of the shaft being known.

What' is here claimed, and desired to be secured by Letters Patcnt,.is'-i The combination ofthe box, hub, or shell B, reverscwedge-shaped blocksC C', and bolts D D', with their nuts E E', or the equivalents of thesedevices, arranged for operation together, substantiallylas and for thepurposes herein set forth.
